DIN EN ISO 4519:2016-08 EN ISO 4519:2016 (E) 4 Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards Institutes (ISO member bodies). The work of developing International Standards is carried out through ISO technica
23、l committees. Every member body interested in a subject for which a technical committee has been set up has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards ad
24、opted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. International Standard ISO 4519 was developed by Technical Committee ISO/TC 107, Metallic and other non-organic coatings, and was circulated to th
25、e member bodies in March 1979. It has been approved by the member bodies of the following countries: Bulgaria Israel South Africa, Rep. of Canada Italy Spain Czechoslovakia Japan Sweden France Korea, Rep, of Switzerland Germany, F.R. Libyan Arab Jamahiriya Turkey Hungary Poland United Kingdom India

27、tes of electrodeposited metallic coatings. It may be applied to related finishes by agreement between the supplier and the purchaser. It is based on ISO 2859 (see also Addendum 1 to ISO 2859). The sampling plans in this International Standard are applicable, but not limited, to the inspection of end
28、 items, components, materials in process and finished products in storage. The plans are intended primarily to be used for a continuing series of lots, but they may also be used for the inspection of isolated lots. However, the assurance given for isolated lots is lower than that given for a continu
29、ing series of lots. This International Standard is not applicable to the sampling and testing of mechanical fasteners having electrodeposited metallic coatings or related finishes, in all the circumstances for which procedures for these components are specified in ISO 3269. The sampling plans given
30、in this International Standard are based on AQLs1)of 1,5 and 4,0 %. Other AQLs may be used if specified in the product specification, in which case reference should be made to ISO 2859 and its Addendum 1. lt is also possible to formulate sampling plans based on inspection by variables. 2 References

DIN EN ISO 4519:2016-08 EN ISO 4519:2016 (E) 6 3.3 inspection by attribute(s) Inspection whereby either the unit of product is simply classified as defective or non-defective, or the number of defects in the unit of product is counted, wit
35、h respect to one or more given requirements. 3.4 unit of product The object inspected either to determine its classification as defective or non-defective, or to count the number of defects. It may be a single article, a pair, a set, a length, an area, an operation, a volume, a component of an end i
36、tem or the end product itself. The unit of product may or may not be the same as the unit of purchase, supply, production, or shipment. 3.5 acceptance number The maximum number of defects or defective units in the sample that will permit acceptance of the inspection lot. 3.6 rejection number The min
37、imum number of defects or defective units in the sample that will cause rejection of the inspection lot. 3.7 inspection lot A collection of coated articles that are of the same kind, that have been produced to the same specifications, that have been coated by a single supplier at one time, or at app
38、roximately the same time, under essentially identical conditions and that are submitted for acceptance or rejection as a group. 3.8 Classification of defects and defectives 3.8.1 method of classifying defects The enumeration of possible defects of the unit of product classified according to their se
39、riousness. A defect is any non-conformance of the unit of product to the specified requirements. Defects are normally grouped into one or more of the following classes; however, defects may be grouped into other classes or into sub-classes within these classes. 3.8.1.1 critical defect A defect that
40、judgement and experience indicate is likely to result in hazardous or unsafe conditions for the individual using, maintaining, or depending upon the unit of product which has an electrodeposited metallic coating or related finish. It may also be a defect in the coating that judgement and experience
41、indicate is likely to prevent performance of the primary function of a major end item. 3.8.1.2 major defect A defect, other than critical, that is likely to result in failure of the finish, or to reduce materially the usability of the unit of product for its intended purpose. DIN EN ISO 4519:2016-08
42、 EN ISO 4519:2016 (E) 7 3.8.1.3 minor defect A defect that is not likely to reduce materially the usability of the unit of product for its intended purpose, or is a departure from established standards having little or no bearing an the effective use or operation of the item which has an electrodepo
43、sited coating or related finish. NOTE Inspection for detection of critical defects may require non-destructive examination of every unit of product in the lot. In this International Standard, all defects not conforming to the specified requirements in the product item specifications for electrodepos
44、ited coatings and related finishes are considered to be major. If specified by the purchaser, the maximum number of defects per hundred items, or the maximum percent defective laid down in this International Standard can be increased for the purpose of sampling inspection of minor defects. 3.8.2 met
45、hod of classifying defectives A defective is a unit of product which contains one or more defects. Defectives are usually classified as follows: 3.8.2.1 critical defective A defective which contains one or more critical defects, and which may contain major or minor defects. 3.8.2.2 major defective A
46、 defective which contains one or more major defects, and which may contain minor defects but no critical defects. 3.8.2.3 minor defective A defective which contains one or more minor defects, but no critical or major defects. 3.9 expression of non-conformance The extent of non-conformance of a produ
47、ct expressed either in terms of percent defective, or in terms of defects per hundred items. 3.10 percent defective One hundred times the number of defective units of product divided by the total number of units of product inspected, i.e. Percent defective =number of units inspectednumber of defecti

49、determine conformance with the acceptance criteria. It may differ from a collection of units of product designated as a lot for other purposes, such as production, shipment, and storage. 4.2 Formation of lots The product shall be assembled into identifiable lots, sub-lots, or in such manner as may be prescribed (see 6.3). Each lot shall, as far as practicable, consist of units of product or separate specimens of the same basic material composition, of a single type, grade or class of the coating or finish, and approximately the same size
